Application Guide (5 Easy Steps)

01
Substrate Preparation

Substrates (concrete, mortar, stone, steel) must be sound, clean and free from laitance, dust, oil, grease and loose particles. Concrete should be dry or mat-damp with no standing water; steel must be de-rusted to Sa 2.5.

02
Mixing

Mix components A+B thoroughly with a slow-speed drill (max ~300 rpm) until uniform in colour, then add component C (where applicable) and mix to a homogeneous, lump-free mortar. Avoid aeration.

03
Application

Work the material firmly onto the prepared substrate within the pot life, pressing well in for full contact. For vertical/overhead work the thixotropic mix is non-sag.

04
Finishing

Compact and finish to the required profile before the pot life ends. Mix only the quantity that can be placed in time.

05
Curing & Cleaning

Protect from rain until cured. Clean tools with the recommended cleaner while the resin is fresh; cured material can only be removed mechanically.

Follow the official Sika Technical Data Sheet for full application details.
